ARTHUR srnvnns, or BUFFALO, new Yomc DRUM-CLEANING MACHINE.

Application filed October 20. 1 927." Scr ia1 No. 227,565.

As is wellknown to those skilled in the art, the most efficient method of cleaning drums, or like containers, is to slightly ro-. tate them on their longitudinal axis while they are being turned endwise on a lateral axis. j

The principal object of my invention has been to provide a machine, for giving a drum the motions above indicated, which simple in design, and convenient and easy to operate. r l j Moreover, my device has but few parts, and is provided with. simple and convenient means for clamping a drum, or other container, thereon.

The above objects and advantages have been accomplished by the device, shown in the accompanying drawings, in which the figure illustrated is a side elevation of the device with portions thereof in section.

My device comprises a bearing pedestal or standard 5 in which is'rotatably mounted a main shaft (5. Mounted between the hear- :ing blocks 7 and 8 of the standard is a tight pulley 9 and a loose pulley 10, by which the device may be driven through the medium of a belt (not shown), The ends of the shaft 6 extend beyond the bearing blocks 7 and 8 for some distance, and rigidlymounted upon each end of this shaft is a frame 15. Each of the frames comprises a body portion 16 having at one end a lateral arm 17, and at the other end a lateral arm 18. The lateral arms 17 and 18 extend beyond the body portion 16 a distance which is slightly greater than the radius of the largest drum or receptacle to be placed within the device.

The lateral arm 18 is provided at its outer end with a bearing 19 in which is rotatably mounted the shaft 20 of a platform 21. The axis of this shaft is preferably arranged at an angle with the axis of the main shaft 6. The platform 21 forms a support for the drums 82 or other receptacles and a bevel gear 22 is either formed on the platform or secured thereto. A collar 23 is carried at the outer end of the shaft 20 for retaining it in place. The lateral arm 17 is provided with a boss 24 in which is centrally mounted an adjusting screw 25. The adjusting screw is provided at its outer end wlth a hand wheel 26- and has its inner end mounted within a flange 27. The inner end of the screw is provided with an annular groove 28 with which the point of a screw 29 engages, whereby the adjusting screw is rotatably attached to the flange. A look nut is carried b, the, screw 25 and has bearing contact with the top face of thelug 24. An arm 31 is provided on the lock nut, whereby it may be conveniently manipulated. l j i The platform 21 is provided on the upper surface with a plurality of spring fingers 3.3. The flange 27 is likewise provided with a plurality of spring fingers 34L. These spring fingers are proportioned so as: to bear against and engagethe head of the drum, or other receptacle inside the chimes usually. formed on. such receptacles, as shown at 35 on the drawing. hen the drumis raised upon the fingers 38 carried by the platform 21, the fingers 34 are brought down to and into contact with the upper head of the drum by means of the screw 25. The screw is then locked in place by meansof the lock nut 80, whereby the drum may be rotated on itslongitudinal axis.

Engaging with thebevcl gear 22 of the platform 21 is a bevel gear pinion 40. This pinion is carried by an auxiliary shaft ll which is rotatably mounted within the body part 16 of the frame and carries at itslouter end a pendulum weight &2, The weight is secured to the. shaft near one of its ends, so that gravitation will. keep it maintained in the position shown in the drawings, whereby the pinion 10 will also be kept from rotating.

It will be clear that when the main shaft 6 is rotated, the frames 15 will be carried around with it and the drums carried by the frames will be tumbled end for end on a lateral axis. As each frame is thus rotated, the weight 12, auxiliary shaft 41, and pinion 40 will be carried around with the frame, but owing to the action of the weight, it, together with the auxiliary shaft and pinion, will be maintained in a substantially nonrotative position, which will cause the bevel gear 22 and the platform 21 to be rotated. The drum is thus rotated slightly on its longitudinal axis while it is being tumbled around on its lateral axis. A chain or any other suitable abrasive object or objects are preferably placed within the drum which is being cleaned, whereby the inner surface of the drum is scoured.

While I have shown and described my machine for cleaning receptacles, it is obvious that the same may be used for mixing both liquid or solid materials. A machine with two frames 15 and their coacting parts is shown and described in the application, but one frame only may be used if desired.

These and other modifications of the details herein shown and: described may be made without departingfrom the spirit of my invention or the scope ofthe appended claims,'and I do not wish, therefore,to be limited to the formhe'rein shown and described, such form being only a preferred form thereof. 3 1 Having thus described my invention What I claim is: r

I 1; A cleaning machineicomprising a main shaft, aframe carried by the shaft, a rotating platform carried at one end of the frame a and having its axis at an angle to the axis of the main shaft, clamping means carried by the opposite end of the frame, and gravity operated means for causing the rotation of the platform when the" frameis being" carried around by the main shaft.

' 2. A cleaning machine comprising a main shaft, a frame carried by the shaft, a rotating platform carried at one end of the frame and having its axisat an angle to the axis of the main shaft, gravity operated means for causing'the rotation of the platform When the frame is being carried around by the main shaft, screw means carried by the opposite end of the frame, and resilient means carried by the platform and by the screw for clamping a drum upon the platform. V I i 3. A cleaning machinecomprising a main shaft, a frame carried by the shaft, a rotating platform carried at one end of the frame and having its axis at right angles to the axis of the main shaft, clamping means car-.

ried at the other end of the frame, fan

auxiliary shaft carried by the frame, gear means for connecting the inner end of the auxiliary shaft with the platform, and a weight carried at the outer end of the auxilary shaft for causing the rotation of the platform when the frame is being carried around by the main shaft.

4. A cleaning machine comprising a main shaft, a frame carried by the shaft, a rotating platform carried at one end of the frame and having its axis at right angles to the axis of themain shaft, the platform-having a gear formed thereon, an auxiliary shaft carried by the frame, a gear pinion carried b the auxiliary shaft'for engaging with the gear formed on the platform, a weight carried by the auxiliary shaft for causing the rotation of the platformwhen'the frame is being carried around by the main shaft, and

clamping means carried by the opposite end screw means carried by the opposite end of the frame, and resilient means carried by the platform and by the screw for clamping a drum-uponthe platform. In testimony whereof, I have hereunto signed my'nameQ J ARTHUR STEVENS.
